Baloye, D, Adesina F, Kufoniyi O.  2021.  A SPATIAL DECISION SUPPORT SYSTEM APPROACH TO SUSTAINABLE PHYSICAL DEVELOPMENT PLANNING IN A BUILT ENVIRONMENT, 2021/10/15. Abstract

To make the MDGs a reality, especially as it affects the built environment, and to conform with the UN Agenda 21 and Habitat Agenda summed up in the concept of urban physical sustainability, there is a need to rapidly improve the quality of decisions on land use, conversion and urban renewal in developing countries, especially with regards to physical developments. The potentials of SDSS in determining optimum sites for physical developments within the built environment was the focus of this study. The SDSS developed took into consideration existing and future planning scenarios with the aim of creating a sustainable built environment. To do this, a framework for capturing existing landuse was generated and the SDSS used to generate physical development expansion scenarios of the Obafemi Awolowo University, Nigeria. The system facilitated integrated procedures for determining optimal sites for incremental physical development in such a way as to minimize impact on other aspects of development. The application of this system shows that planning especially as it relate to the urban environment can be made more flexible, dynamic and responsive to timely decisions on geographic space.

This study fabricated and characterized a self-sustaining hydrogenous content clay-polyethylene composite opted for ionizing radiation shielding. Composites designated A–G were fabricated each containing 0–30 wt% of recycled low density polyethylene (LDPE), respectively. To know the effects of the incorporated LDPE on the morphology, microstructural, compressive strength, thermal property and displacement effect on the vital elements were studied using scanning electron microscopy (SEM), X-ray diffractometry (XRD), universal mechanical testing machine, differential thermal analysis (DTA), Rutherford backscattering (RBS) technique and particle induced X-ray emission (PIXE), respectively. The bulk densities of the clay composites ranged between 1.341 and 2.030 g/cm3. The samples’ XRD analysis revealed similar patterns, with a sharp and prominent peak at angle 2θ equals ~26.11°, which matched with card number 16-0606 of the Joint Committee on Powder Diffraction Standards (JCPDS) that represents Aluminum Silicate Hydroxide (Al2Si2O5(OH)4), a basic formula for Kaolin clay. The compressive strength ranged between 2.52 and 5.53 MPa. The ratio of Si to Al in each composite is about 1:1. The dehydroxylation temperature for samples ranged between 443.23 °C and 555.23 °C.

Abstract

The aim of the study was to assess if there were significant differences in the adoption of COVID-19 risk preventive behaviors and experience of food insecurity by people living with and without HIV in Nigeria. This was a cross-sectional study that recruited a convenience sample of 4471 (20.5% HIV positive) adults in Nigeria. Binary logistic regression analysis was conducted to test the associations between the explanatory variable (HIV positive and non-positive status) and the outcome variables-COVID-19 related behavior changes (physical distancing, isolation/quarantine, working remotely) and food insecurity (hungry but did not eat, cut the size of meals/skip meals) controlling for age, sex at birth, COVID-19 status, and medical status of respondents. Significantly fewer people living with HIV (PLWH) reported a positive COVID-19 test result; and had lower odds of practicing COVID-19 risk preventive behaviors. In comparison with those living without HIV, PLWH had higher odds of cutting meal sizes as a food security measure (AOR: 3.18; 95% CI 2.60-3.88) and lower odds of being hungry and not eating (AOR: 0.24; 95% CI 0.20-0.30). In conclusion, associations between HIV status, COVID-19 preventive behaviors and food security are highly complex and warrant further in-depth to unravel the incongruities identified.

Abstract

An online survey was conducted to identify factors associated with financial insecurity, food insecurity and poor quality of daily lives of adults in Nigeria during the first wave of the COVID-19 pandemic. The associations between the outcome (experience of financial loss, changes in food intake and impact of the pandemic on daily lives) and the explanatory (age, sex, education level, anxiety, depression, HIV status) variables were determined using logistic regression analysis. Of the 4439 respondents, 2487 (56.0%) were financially insecure, 907 (20.4%) decreased food intake and 4029 (90.8%) had their daily life negatively impacted. Males (AOR:0.84), people who felt depressed (AOR:0.62) and people living with HIV -PLHIV- (AOR:0.70) had significantly lower odds of financial insecurity. Older respondents (AOR:1.01) had significantly higher odds of financial insecurity. Those depressed (AOR:0.62) and PLHIV (AOR:0.55) had significantly lower odds of reporting decreased food intake. Respondents who felt anxious (AOR:0.07), depressed (AOR: 0.48) and who were PLHIV (AOR:0.68) had significantly lower odds of reporting a negative impact of the pandemic on their daily lives. We concluded the study findings may reflect a complex relationship between financial insecurity, food insecurity, poor quality of life, mental health, and socioeconomic status of adults living in Nigeria during the COVID-19 pandemic.

Adedoja, O, Samways M, Kehinde T.  2021.  Age class of alien tree stands retained for mammal protection have differential effects on flower-visiting insect assemblages, 2021/07/10. Abstract

• Limited sunlight reduces plant productivity and foraging activities of pollinators, such as when alien trees shade out native flowering plants. The conservation management response is to remove the impoverishing effect of the alien tree canopy. However, alien trees can provide benefit for certain species when they provide significant scarce resources. We assess how flower-visiting insects respond to shading from young, small-sized, open canopy vs. mature, tall, closed-canopy alien pine trees retained specifically as refuges for certain rare mammals.• We sampled flower–visitor species diversity and interactions at various distances from pine stands of both sizes in a matrix of low sclerophyllous natural vegetation. We sampled flower–visitors using coloured pan traps and estimated flower–visitor interactions and flower diversity.
• Reduction in percentage light reaching the understorey significantly reduced flower abundance, with zero flowers in tall pine understorey. Flower–visitor species composition differed across sampling locations with increasing distance from tall pine understorey. Although pine tree size led to a decline in flower–visitor interaction frequency and network specialisation in all pine tree stands, some bee species that are mostly tree nesters, were observed in unique interactions in association with tall pines only.
• We show that alien pines, especially tall trees, have an impoverishing effect on flowering plants and flower–visitors. However, these trees also confer benefit to specialised groups such as tree-nesting bees. While active alien pine removal is encouraged where the trees are actively invading, maintaining well-contained small stands is of value for two different taxa of conservation concern.

Background and objectives:Non-communicable diseases have emerged as major public health concerns in developing nations, where communicable diseases used to be the major contributor to the public health burden. Diabetes and hypertension contribute significantly to this menace, and they are largely undiagnosed in the affected population. We determined the prevalence of previously diagnosed and undiagnosed hypertension and diabetes mellitus in adult Nigerians.
Methods:
Participants who presented in response to advertisement for the study and gave informed consent were recruited using convenience sampling. Data was collected using a proforma to obtain salient medical and social history. Anthropometric and blood pressure measurements were done. Capillary blood was taken for initial glucose measurements. Oral glucose tolerance test (OGTT) was subsequently done in non-diabetics with elevated blood glucose to confirm the diagnosis of diabetes.
Results:
One hundred and thirty-six participants with age range 24 - 90 years were recruited for the study. Participants were mainly females (61.8%). Prevalence of diabetes among study participants was 19.9% (previously diagnosed -16.9% vs undiagnosed - 3.0%) with higher occurrence among males. Hypertension was found in 50.7% of participants; 28.7% were on treatment for hypertension, while 22.0% were newly diagnosed. Diabetes was associated with older age and elevated systolic blood pressure while hypertension was associated with older age, obesity and elevated blood glucose.
Conclusion:
This study showed a high occurrence of diabetes and hypertension among adult Nigerians; hence efforts to address these should be intensified. Targeted screening of people at risk for non-communicable diseases is an added benefit.
